French artist, Eltono has been working in the public space for over fifteen years, notably through mural painting. He now plays with lines to repeat this adaptable form and make it a graphic motif constant enough to be identified but at the same time changeable enough to fit a given context. It is the way he articulates the lines and the colors he uses that allows him to adapt to the surfaces he paints on. The inhabitants of the Grette and Butte districts were able to create a mural with the artist Eltono. These painting workshops were a good opportunity for the participants and the parents accompanying their children to meet Eltono and to question him on his artistic practice.
